Felix and Penn – GTM Engineering StackOptimise Course

Felix and Penn – GTM Engineering StackOptimise Course

In a data-driven world where every click, scroll, and action matters, tag management and engineering precision are no longer optional — they’re essential. If you’re serious about advanced tracking, conversion optimization, and building robust analytics infrastructure, the GTM Engineering StackOptimise Course by Felix and Penn is your go-to blueprint.

This course delivers hardcore GTM engineering skills — not surface-level walkthroughs or outdated setups. Whether you’re a data analyst, technical marketer, CRO specialist, or product team lead, this course gives you the technical fluency to optimize tracking at scale using Google Tag Manager (GTM) and the modern analytics stack.

From custom data layers to event triggers, from server-side GTM to clean schema deployment, Felix and Penn teach you how to engineer a tracking system that works across tools, devices, and user journeys.

Why GTM Engineering Matters in 2025

In today’s multi-device, privacy-conscious environment, tracking isn’t getting easier — it’s getting more complex. Browser restrictions, cookie limitations, and shifting attribution rules demand precise and flexible tag implementation.

That’s why companies are moving beyond basic GTM setups. They need engineered stacks — purpose-built frameworks for scalable, compliant, and reliable data tracking. Felix and Penn’s StackOptimise course shows you how to build and maintain that kind of system.

Whether you’re setting up a robust conversion API, building event-driven tracking, or optimizing eCommerce data flows, this course has the hands-on instruction you’ve been waiting for.

What You’ll Learn in GTM StackOptimise

1. GTM Engineering Foundations

Understand the architecture of Google Tag Manager from an engineering perspective. Learn how GTM containers, workspaces, environments, and debug tools interact under the hood — and how to use them efficiently.

2. Custom Data Layer Engineering

Go beyond the basics. Learn how to design and implement robust `dataLayer` structures for websites and apps, including event schemas, eCommerce object tracking, and cross-domain sessions. Includes real implementation use cases and developer handoff strategies.

3. Event Tracking & Trigger Logic

Discover how to build efficient and reliable triggers for scroll depth, click events, form submissions, video views, page timing, and custom JavaScript events. Felix and Penn teach you how to combine multiple triggers for precise audience segmentation and behavior tracking.

4. Advanced Tag Management

Understand how to build scalable tag templates for Google Ads, Facebook Pixel, LinkedIn Insight Tag, Hotjar, GA4, server-side events, and more. You’ll also learn to delay tags for performance, bundle conditions, and ensure GDPR and CCPA compliance.

5. GA4 + Server-Side Tagging

The future of measurement is server-side. This course shows you how to set up Server-Side GTM (sGTM) with GA4, using custom client containers, first-party cookies, and BigQuery integrations. Learn how to maintain clean data pipelines and avoid duplicate tracking.

6. Debugging & Quality Assurance

Tracking means nothing if it doesn’t work right. Learn how to test, debug, and QA your GTM setups using browser tools, GTM’s preview mode, Google Tag Assistant, and Felix & Penn’s exclusive custom debugging methods.

7. Stack Integration with Marketing & Product Tools

You’ll learn how to align your GTM strategy with tools like Segment, Mixpanel, Amplitude, Klaviyo, and other downstream platforms. Build your stack once — and distribute clean event data everywhere.

8. Real-World Use Cases & Engineering Templates

This course includes code samples, JSON container templates, tag blueprints, and system diagrams for different business models — eCommerce, SaaS, mobile apps, lead gen, and more.

What Students Are Saying

> “This course finally gave me clarity on GTM at a deep level. No more hacks. I can now track everything my product team needs — cleanly and reliably.”— Priya S.

> “I’ve taken several GTM courses, but none go into this level of engineering. The debugging and server-side modules alone are worth the cost.”— Diego M.

> “Felix and Penn are the real deal. Their StackOptimise approach transformed the way we handle data layers and GTM governance across teams.”— Martin K.

In 2025, data quality = marketing performance. If your tagging is messy, your decisions are off. If your GTM isn’t structured for growth, you’re leaving insights and revenue on the table.

Felix and Penn’s GTM Engineering StackOptimise Course is the smartest investment you can make in your analytics skills. It gives you not just the tools — but the technical clarity and confidence to architect a future-proof, ROI-focused data infrastructure.

Whether you manage one brand or many, this course helps you build better stacks, make better decisions, and drive better results.
